Abstract (en)
[origin: WO2007121542A1] High-speed steel for saw blades, presenting a composition of alloy elements consisting, in mass percentage, of Carbon between 0.5 and 1.5; Chromium between 1.0 and 10.0; equivalent Tungsten, given by 2Mo+W relation, between 3.0 and 10.0; Niobium between 0.5 and 2.0. Niobium may be partially or fully replaced with Vanadium, at a ratio of 2% Niobium to each 1% Vanadium; Vanadium between 0.3 and 2.0. Vanadium may be partially or fully replaced with Niobium, at a ratio of 2% Niobium to each 1% Vanadium, Silicon between 0.3 and 3.5. Silicon may be partially or fully replaced with Aluminum, at a 1:1 ratio; Cobalt lower than 8, the remaining substantially Fe and impurities inevitable to the preparation process.
